This is my first quality sleeping bag (non-chain store). I am impressed with it's design and features. The pillow sleeve worked great with a rolled up fleece. The zipper worked well. It also has adjustable straps for a sleeping mat which kept me centered on my Thermarest all night. The Long bag was more than enough room for me at 6', 220lbs.
